Feel the power with FLEXTRON PRO
For maximum energy return when trail running, we developed FLEXTRON PRO. Built for those who like their trails technical and their pace fast, it provides the precise torsional stability needed for confident, high-speed performance.
FLEXTRON PRO stores and releases energy with every step to create explosive toe-off and smooth, responsive propulsion.
"Great shoes. Used them for my first Ultra and they held up really well. No pain whatsoever in spite of having issues with my calves and feet before."

Great trail shoe
"Awesome shoe, used it for the VT100 and had zero foot issues. Comfortable right out of the box, my first run with them was 20+ miles and they felt great. I’ve yet to have any meaningful chafe or blistering with 300+ miles on board.
The only drawbacks I’ve noticed are: a weird plasticy smell that lingers and a bit of instability on highly technical terrain. It’s not ideal for gnarly rocks and roots but they really excel on most other trail."

"Very happy so far , comfortable and stable up and down hill . Good grip . Let’s see how long they last as I have only done about 40km in them."

Very pleased.
"Very happy with the shoe overall, I noticed some small imperfections in the build quality.
Toe box was nice and wide and the outsole is very grippy. The ventilation is very nice.
The black and white looks awesome."
